ABSTRACT:
A dual reservoir access port includes a metal casing having a top surface with recessed, open proximal and distal fluid reservoirs. Projecting from the casing on the side of the distal fluid reservoir opposite from the proximal fluid reservoir is a dual prong metal outlet stem. The distal fluid reservoir is carried within an open-topped basket that is disposed in a cup formed in the top surface of the casing. A first fluid flow pathway extends from the proximal fluid reservoir, between the basket and the wall of the distal cup, to the outlet stem. A second fluid flow pathway extends directly from the distal fluid reservoir to the outlet stem. A needle-penetrable compound septum is disposed against the casing simultaneously closing the top of the proximal fluid reservoir and the top of the distal fluid reservoir. A plastic jacket clamps the septum against the casing and compresses the periphery of the septum to effect a fluid seal by the septum of each of the fluid reservoirs. An annular sleeve mechanically locks and fluid couples a dual lumen catheter to the outlet stem. The catheter may be chosen from among three dual lumen catheters, each having a combination of material composition and lumen configuration that is distinct from those of the others of the catheters.
